Further information

$ zellij
$ while :; do; tr -dc A-Za-z0-9 </dev/urandom | head -c 200 ; echo ''; done
wait a while
CTRL+C

select some text - it will be very slow

another quicker way to repro is usually just a simple rg a as it's not as slow as generating random data - but that would have included sensitive stuff in the debug log

$ zellij
$ rg a
CTRL+C

select some text - it will be very slow

it gets really bad at around 50k lines
